A scalable design system for an AI-powered real estate platform

Theo builds an AI operating system for real estate ownership, replacing the fragmented, pen-and-paper workflows landlords have relied on for decades with one connected interface. Three years ago, as hallo theo, the Berlin startup set out to fix this notoriously analog industry — and has since scaled to 20,000 homes across five cities in Germany.

A Color Bright redesigned the brand from the ground up to match that momentum: a new logo, a new visual language, and a new marketing website, designed and built alongside it. hallo theo became Theo — shorter, more confident, and built for the scale ahead.

My main focus was building a scalable design system based on the brand's updated visual identity, giving the new product a consistent foundation to grow on.

Project Goals

  1. Modernize the application by reworking the navigation and app chrome while defining layout guidelines1
  2. Envision future product features to make sure the design system covers enough ground2
  3. Build the design system in a agent friendly way to speed up implementation time3
